Be it known that 1, MARTIN Saxon, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Air planes, of which the following is a specification.

My invention has relation to improvements in airplanes, and consists in the novel details of construction more fully set forth in the specification and pointed out in the claim. 1

The object of the present invention is to provide an airplane that shall be equipped with propellers on both sides of the fore part of the airplane body or fuselage, the propellers being adapted to revolve in a plane parallel to the direction of travel, said propellers in addition to propelling the plane forward exerting a lifting tendency to assist in maintaining the plane in flight. A further object is to arch the supporting planes transversely to the direction of travel to assist in stabilizing the machine, the upper plane being provided with a hinged section that may be swung upwardly to take the air at an angle for the purpose of elevating the plane when so desired. Further and other advantages will be better apparent from a detailed description of the invention in connection with the accompanying drawings in which Figure 1 is a side elevation of my improved airplane; 2 is a front elevation thereof; Fig. 3 is a plan view of the same; Fig. f is a horisontal section on the line dl of Fig. lfshowinpgthe controls; and Fig. 5 is a vertical section through a part of the 'Jt'uselage showing the controls in elevation. I

Referring to the drawings 1 represents the body or fuselage of the airplane, 2 the lower plane secured thereto, said plane being transversely arched and supporting the upper plane 3 by means of struts i, 1, etc., suitably braced by guy wires 5, 5, 5, etc. T he fuselage 1 is tapered at the front for offering less resistance to the air, and carries a tail plane 6 at its rear end, the tail plane also being arched transversely.

Fixed to the end of the fuselage is a rudder-bar 7 to which is hinged a rudder 8, the latter being): controlled by wires 9, 9 extending forwardly within the fuselage to a foot lever 10. which is operated from the drivers seat 11. An engine 12 is mounted 1921. Serial No. 472,725.

in thefore part of the fuselage, the engine shaft 13 having a gear 14: mounted on it, said gear driving a second gear 15 mounted on a counter-shaft l6, shaft 16 having a bevel-gear'l? adapted to drive a bevel gear 18 mounted on a propeller shaft 19 rotatable in suitable bearings 20, the propeller shaft 19 passing through the nose of the fuselage and carrying on its ends outside of the fuselage propellers 21, 21, each of which consists of four blades 22 disposed at right angles, the outer ends of the blades 22 terminating 1n spoon-shaped heads 23 adapted to pick up the air as the propellers are revolved, thus driving the machine forward. The heads 23 on the downward part of their revolution also operate to exert a lifting tendency onthe plane, thus assisting to maintain the same in flight. A carriage 2 .2 is mounted beneath the fore part of the fuse lags, and a skid 25 is mounted beneath the tail thereof, the carriage and skid serving to facilitate starting and landing, as is well understood in the art.

The plane 3 is provided with a forward section 3 hinged to the plane 3 by means of a continuous hinge 26, the section 3 being tiltable along the hinge 26 by means of a pair of wires 27 secured atthe front corners of the section 3', each of said wires extend ing from the corner of the section 3 over a pulley 28 mounted on a bracket 29 fixed to the top of the plane 3, said wire 27 continuing from the pulley .98 through an opening 0 in the plane 3, thence to a double grooved sheave 30 mounted on the inside of the fuselage, the wire 27 passing around the sheave 30 two turns and then over a sheave 31 mounted on a shaft 32 extending across 3 the inside of the fuselage, and from the sheave 31 the wire continues to a double grooved sheave 33 adjacent the sheave 30, and thence back to the corner of the plane 3 opposite the point where the wire started. In flight when the operator desires to ascend he pulls forward on a lever 3 1 keyed to the shaft 32, thus rotating the sheave 31 in the direction of the arrow (Fig. 5) the result of which is to pull downwardly on the side of the wire 27 that is passed over the sheave 30, releasing the opposite side of the wire and tilting the section 3' of the plane upwardly a suficient distance to cause the planeto veer upwardly, thus climbing in altitude until the desired altitude is reached, when the lever 3% is again swung back to restore the section 3 to a horizontal plane. v y Y From the foregoing it will be apparent that I have provided an airplane that possesses facilities for rapidly increasing its altitude when desired, and. one, the propellers of which, in addition to propelling,

tain the same.

Having described my invention, 1 claim: An airplane provided with a fuselage two superposed transversely arched planes, the upper plane extending forwardly beyond the lower plane, a transversely arched exert a lifting tendency on the plane to susyond the lower plane.

In testirnony whereof I hereunto afiix my signature.
